The Office of Labor-Management Standards (OLMS) of the U.S. Department of Labor administers and enforces most provisions of the Labor-Management Reporting and Disclosure Act of 1959 (LMRDA). The LMRDA primarily promotes union democracy and financial integrity in private sector labor unions through standards for union officer elections and union trusteeships and safeguards for union assets. Additionally, the LMRDA promotes labor union and labor-management transparency through reporting and disclosure requirements for labor unions and their officials, employers, labor relations consultants, and surety companies.

OLMS also administers provisions of the Civil Service Reform Act of 1978 and the Foreign Service Act of 1980, which extend comparable protections to Federal labor unions. OLMS does not have jurisdiction over unions representing solely state, county, or municipal employees. In addition, the Division of Statutory Programs (DSP) administers DOL responsibilities under the Federal Transit Act by ensuring that fair and equitable arrangements protecting mass transit employees are in place before the release of Federal transit grant funds.
